What Captions Can Capture is a term that refers to the ability of captions to capture AUDIO content in a video. Captions are text that is synchronized with the AUDIO of a video, allowing viewers to understand what is being said even if they cannot hear the AUDIO. Captions can also be used to provide additional information about the video, such as the names of people or places mentioned in the AUDIO. Captions can be used to make videos more accessible to people who are deaf or hard of hearing, as well as those who do not speak the language of the video. The term AUDIO is a five-letter word that refers to sound that is audible to the human ear.
